Fiber-optic biosensor to assess circulating phagocyte activity by chemiluminescence.

We describe herein the construction of a novel computerized multi-sample temperature-controlled luminometer for a fiber array-based biosensor to monitor circulating phagocyte activity. It can perform simultaneously integral measurements of chemiluminescence emitted from up to six samples containing less than 0.5 microl whole blood while the samples and detector do not change their position during the measurement cycle.
